Abstract: Various implementations disclosed herein include devices, systems, and methods that provide XR in which virtual objects are positioned based on the accuracy of localizing an electronic device in a physical environment. In some implementations, the technique assesses the accuracy of localization (e.g., centimeter-level accuracy, room-level accuracy, and building-level accuracy) and dynamically adjusts a display strategy. In some implementations, the technique determines a condition causing inaccuracy (e.g., a semantic condition such as “too fast”, “too far”, “too dark”), and provides a notification (e.g., “too fast-slow down”, “too far-move closer”, “too dark-turn on a light”) at the electronic device based on the condition causing the inaccuracy in the localization.

Abstract: An apparatus includes a primary camera sensor configured to capture images having a first resolution, a primary processing circuit configured to process images captured by the primary camera sensor, a secondary camera sensor configured to capture images having a second resolution, and a secondary processing circuit configured to process images captured by the secondary camera sensor. In response to a determination that a particular object of interest is included in a particular image, the secondary processing circuit may be further configured to cause the primary processing circuit and the primary camera sensor to exit a reduced power mode. The primary camera sensor may be further configured, in response to the exiting, to capture a different image. The primary processing circuit may also be configured to process the different image to validate the particular object of interest.

Abstract: Various implementations disclosed herein include devices, systems, and methods that estimate a location of a light source based on ambient light data. For example, an example process may include acquiring ambient light data from an ambient light sensor (ALS) during movement of a device in a physical environment, acquiring motion data from a motion sensor during the movement of the device, determining, based on the ambient light data and the motion data, estimates of three-dimensional (3D) locations of a light source with respect to the device during the movement of the device, and tracking a location of the device in a 3D coordinate system during the movement of the device based on the estimates of the 3D locations of the light source with respect to the device during the movement of the device.

Abstract: A method includes sensing a plurality of luminance values associated with ambient light from a physical environment. The plurality of luminance values quantifies the ambient light arriving at a see-through display. The method includes identifying respective portions of the plurality of luminance values, across the see-through display, based on corresponding portions of rendered image data. The method includes modifying one or more of the respective portions of the plurality of luminance values based on a function of predetermined display characteristics associated with the rendered image data, in order to generate one or more modified portions of the plurality of luminance values. The method includes modifying the corresponding portions of the rendered image data in order to generate display data, based on the one or more modified portions of the plurality of luminance values. The method includes displaying, on the see-through display, the display data.

Abstract: In accordance with some implementations, a method is performed at an electronic device with one or more processors, a non-transitory memory, and a see-through display. The method includes determining a plurality of light superposition characteristic values associated with ambient light from a physical environment. The plurality of light superposition characteristic values quantifies the ambient light. The method includes modifying image data in order to generate modified image data, based on a function of the plurality of light superposition characteristic values and a reference perceptual gamut. The method includes transforming the modified image data into display data based on a function of a portion of the plurality of light superposition characteristic values and a reference physical gamut that is associated with the see-through display. The method includes displaying the display data on the see-through display.

Abstract: Various implementations disclosed herein include devices, systems, and methods that match image portions of a first set of image portions and image portions of another set of image portions. This may be performed in a such a way that the sum of descriptor distances of the matched image portions is optimized in a globally optimal way. In some implementations, the matching is subject to one or more constraints, e.g., ensuring that each image portion of the first data set is matched with at least one image portion of the second data set and ensuring that each image portion of the second data set is matched with only one image portion of the first data set.

Abstract: Various implementations disclosed herein include devices, systems, and methods that use an object as a background for virtual content. Some implementations involve obtaining an image of a physical environment. A location of a surface of an object is detected based on the image. A virtual content location to display virtual content is determined, where the virtual content location corresponds to the location of the surface of the object. Then, a view of the physical environment and virtual content displayed at the virtual content location is provided.

The method includes sensing a plurality of light superposition characteristic values associated with the ambient light that quantifies the ambient light. The method includes determining a plurality of display correction values associated with the electronic device based on the plurality of light superposition characteristic values and predetermined display characteristics of the representation of the object. The method includes generating, from the rendered image data, display data for the see-through display in accordance with the plurality of display correction values in order to satisfy the predetermined display characteristics of the representation of the object within a performance threshold.

Abstract: Various implementations disclosed herein include devices, systems, and methods that provide measurement techniques for electronic devices such as optical see-through head mounted devices. In some implementations, a line of sight technique is used to identify a 3D position of a measurement point to enable measurement of an object in a 3D environment. In some implementations, different measurement point identification techniques are automatically selected and used to identify a 3D position of a measurement point to enable measurement of an object in a 3D environment. In some implementations, a 3D position of a measurement point is identified to enable measurement of an object in a 3D environment, where the measurement point is identified by selecting from multiple candidates that are determined using different measurement point selection techniques.
